JOHN-S. ERIKSON, OF CHICAGO, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 778,960, dated January 3, 1905.

Application filed July 25, 1904. Serial No. 217,956.

To all whom, it may concern:

Be it known that I, JOHN S. ERIKsON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Combined Tater-Heater and Garbage- Crematory, of which the following is a specification, reference being had therein to the ac: companying drawings.

My invention has reference to a combined garbage-crematory and water-heater, and has for its objects generally to improve apparatus of this character and increase the effectiveness of the same, as well as to reduce the quantity of coal .or other fuel usually employed for heating the water by utilizing the burning garbage to assist in this purpose.

My combined water-heater and garbagecreinatory is particularly, though not necessarily, adapted for use in apartment or flat buildings where it is the practice to serve the tenants with hot water at all times, and by means of the same the garbage may be consumed on the premises and at the same time be utilized to aid in heating the water supplied to the tenants.

The invention consists of the construction and arrangement of parts hereinafter particularly described, and pointed out in the apbrick built up to a suitable height and providing side walls 11, rear wall 12, and crown of roof 13. The side walls 11 are set back or recessed on their inner face to provide the lower ledges 14 and upper ledges 15, designed to support the tubes of the water-heating apparatus, as hereinafter explained, and forming the ash-pit 16, intermediate combustionchamber 17, and garbage-chamber 18. A

smoke-stack 19 passes through the crown 13 to carry off the products of combustion and resultant gases. The front wall of the shell 10 is shown in the present instance as consisting of a plate 20, extending the height of the side wall and provided with suitable openings to the ash-pit, combustion-chamber, and garbage-chamber, such openings being closed by hinged doors 21, 22, and 23. Resting in notches formed in the ledges 14 is a suitable grate 24, under which the ash-pit 16 is located, the combustion-chamber 17 being located between such grate and the ledge 15. The grate 24 may be of any suitable character, such as that illustrated, and consisting of rocking grate-bars, which are operated by a lever 25, projecting through a slot 26 in the front plate 20.

Resting on each ledge 14 and extending along the adjacent side wall is a drum or header 27, which is spaced, as shown in Fig. 2, from such wall. Communicating with each of the drums 27 are vertical tubes 28,, shown as seven in number, which connect at their upper ends with transverse tubes 29, the ends of which rest upon and are supportedby the ledges 15. The tubes 29 provide a grating upon which the garbage is placed and are suitably spaced apart, as shown in Fig. 4, to permit of the ready access to the garbagechamber of the heat and flames from the fuel in the combustion-chamber and so as not to interfere with the draft, as well as to enable the garbage as it is dried and consumed to pass between the tubes and fall upon the bed of burning fuel in the combustion-chamber. Connected to the ends of the tubes 29 at one side of the shell 10 are vertical tubes 30, which 'are connected at their upper ends to horizontal tubes 31 near the upper end of the shell and communicating with a drum 32, which is shown in Fig.2 as located centrally of the walls 11. In its preferred form and as shown in Fig. 2 the opposite ends of the tubes 29 are also connected to vertical tubes 33, communicating at their upper ends with horizontal tubes 34, also entering the drum 32. As shown in Fig. 2, the vertical tubes 28, 30, and 33 and horizontal tubes 31 and 34 are spaced from the walls of the shell so as to permit the heat and flames from the burning fuel and garbage to pass entirely around or on all sides of such tubes, thereby utilizing the heat generated to the maximum degree. The ledges 14c and 15 serve to properly support the tubes and prevent the same from sagging down or becoming displaced and causing leakage. By the construction illustrated the tubes 28 and 29 inclose the combustion-chamber 17 at opposite sides and top thereof, and the tubes 29,

30, 31, 33, and 3st form a substantially rectangular series of water-tubes inclosing the garbage-chamber at the top, bottom, and sides, whereby the heat generated by the burning fuel and garbage is utilized in a very effectual manner.

A water-storage tank or reservoir, such as 35, may be employed, and cold water is supplied therefrom to the tubes of the heating apparatus by means of pipes 36, which lead from the bottom of the reservoir and enter the rear ends of the drums 27, and this water after circulating through the tubes within the shell finally enters the drum 32, from which it is led by a pipe 37 into the reservoir near the top of the latter. Fresh water is supplied to the reservoir 35 by an inlet-pipe 38, which terminates-near the bottom of the reservoir near the pipes 36, and hot water is drawn from the reservoir by a pipe 39, leading from the top of the same.

As sediment is apt to rapidly accumulate, provision is made for readily cleaning the tubes of such sediment. To this end the front ends of the drums 27 are provided with removable plugs 40, and as the sediment will gravitate through the tubes downwardly into the drums 27 these drums may be readily cleaned by removing the plugs. The upper drum 32 may also be provided with a removable plug tl, as shown.

The garbage is introduced into the garbageburning chamber through the door 23 and is deposited on the grate-tubes 29. If this garbage is in a moist or wet condition, it soon becomes dry, owing to the heat generated in the combustion-chamber 17, and then ignites, and after being more or less consumed falls between the grate-tubes 29 onto the bed of fire in the combustion-chamber 17 where it is entirely consumed, and while the garbage is burning in the garbage-chamber the heat derived therefrom is taken up by the water in the tubes inclosing the burning garbage. By this construction the efiectiveness of the heat from the combustion-chamber is increased by reason of its having to pass around the tubes in the garbage-chamber, as well as the tubes It is obvious that various modifications may be made with regard to the location and arrangement of the tubes of the apparatus, and it is therefore to be understood that I do not limit myself to the exact arrangement shown. 7

Having described my invention, what I claim is 1. In a combined water-heater and garbagecrematory, the combination with a shell providing a combustion-chamber and a garbageconsuming chamber, of vertical tubes at the opposite sides of the garbage-chamber connected at their upper ends, horizontal tubes connecting the lower ends of the vertical tubes and forming a grate to receive the garbage,

ledges at the sides of the shell for supportingthe connected tubes in the garbage-chamber, and depending tubes located at opposite sides of the combustion-chamber and communicating with the grate-tubes.

2. In a combined water-heater and garbagecrematory, the combination with a. shell providing an ash-pit, a garbage-chamber and an intermediate combustion-chamber, of vertical tubes located at opposite sides of the combustion-chamber, horizontal tubes forming a grate for the garbage-chamber and which are in communication with the vertical tubes, vertical tubes at opposite sides of the garbagechamber and connected with the grate-tubes, a centrally-located drum within and at the top of the garbage-chamber, and substantially horizontal tubes connecting the vertical garbage-chamber tubes with the said drum.

3. In a combined water-heater and garbagecrematory, the combination with a shell formed with upper and lower inwardlyprojecting ledges in its side walls and providing an ashpit, a garbage-chamber and an intermediate combustion-chamber, a grate for the combustion chamber, drums resting on the lower ledges, means for supplying water to the drums, vertical tubes communicating with the drums and located adjacent to but spaced from the side walls of the combustion-chamber, spaced transverse tubes resting upon the upper ledges and communicating with the vertical tubes and providing a grate to receive the garbage, vertical tubes located adjacent to but spaced from the side walls of the garbagechamber and communicating with the transverse tubes, a centrally-disposed drum at the upper end of the garbage-chamber, transverse tubes connecting the upper ends of the vertical tubes in the garbage-chamber with the latter drum, and a water-discharge leading from such drum.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN S. ERIKSON.
